Interface MultiBlockCipher

All Superinterfaces:
  BlockCipher

All Known Subinterfaces:
  CBCModeCipher, CFBModeCipher, CTRModeCipher

All Known Implementing Classes:
  CBCBlockCipher, CFBBlockCipher, DefaultMultiBlockCipher, SICBlockCipher

public interface MultiBlockCipher
extends BlockCipher

Base interface for a cipher engine capable of processing multiple blocks at a time.

Method Summary
`int` | `getMultiBlockSize()` Return the multi-block size for this cipher (in bytes).
`int` | `processBlocks(byte[] in, int inOff, int blockCount, byte[] out, int outOff)` Process blockCount blocks from input in offset inOff and place the output in out from offset outOff.

Method Detail

### getMultiBlockSize

    public int getMultiBlockSize()

  Return the multi-block size for this cipher (in bytes).

  Returns:
    the multi-block size for this cipher in bytes.

### processBlocks

    public int processBlocks(byte[] in,
                             int inOff,
                             int blockCount,
                             byte[] out,
                             int outOff)
                      throws DataLengthException,
                             java.lang.IllegalStateException

  Process blockCount blocks from input in offset inOff and place the output in out from offset outOff.

  Parameters:
    `in` - input data array.
    `inOff` - start of input data in in.
    `blockCount` - number of blocks to be processed.
    `out` - output data array.
    `outOff` - start position for output data.
  Returns:
    number of bytes written to out.
  Throws:
    `DataLengthException`
    `java.lang.IllegalStateException`
